The utility model is by the design of described fan base, and its accessible effect comprises:

1. easily assembling: fan base of the present utility model is to utilize the penetration hole in the fan body substrate and the affixed combination of the direct contraposition of protuberance of body, when affixed operation (as welding), because of protuberance and relative penetration hole contraposition assembled state, the displacement that produces in the time of can effectively avoiding weld job, and fan base is with the set tubular junction of body closed end, in order to the direct winding of rotating shaft one end that fan is provided location, need not can reach by other extra components, therefore, make the combination of fan body and body and the winding operation of rotating shaft, have splendid assembling convenience.

2. reduce the defective of fan base contraposition off-centre: fan base of the present utility model is to utilize the protuberance of penetration hole in the fan body substrate and body corresponding to bit combination, after can making the affixed combination of fan body and body, be applied in the fan, can effectively reduce the off-centre of its rotating center, guarantee that fan base is applied to be able in the fan steady rotation.

3. weight reduction, load when reducing fan running: same as above, fan base of the present utility model is to utilize the protuberance of penetration hole in the fan body substrate and body corresponding to bit combination, design by the fan body penetration hole, reduce the material of its entity, and then fan base is applied in the fan, because of fan base weight reduces, fan stator must produce the magneto drive fan base load also alleviate relatively, reach energy-conservation effect.

In addition, another purpose of the present utility model is further to make the body of fan base form recess connection containing space at its closed end inner side surface, in order to enlarge the space in the described body, can be suitable for the assembling of the magnetic drive assembly of multiple class with this, and because the expansion of inner space can make the rotation of fan have better radiating effect.
